DON'T DIE! Ring is a drop and if you die after defeating the Deep Accursed before collecting it the ring will be lost!!! For strategy: A safe kill is if you lure it to the Aldrich boss battle room and then kill it with distant attacks. And I discovered today you can hit it through the golden door. Making it another safe method to kill it. (used demon great axe).

I have killed the deep accursed at the described location but I must have either missed looting the ring and it disappeared or I didnt get it at all. Not sure, but the accursed is dead and the ring is nowhere to be found for me.
